A lion can hunt because they come with weapons biologically attached. Humans not so much. And even you could fashion a spear with little effort. Which by your definition would make you a apex predator. And it did so for millennia.

I'm an old toolmaker that still has a small shop. I could make firearms from scratch if I wanted to. There is nothing special or complex about them. But I choose to purchase them from stores. So perhaps that demotes me from being a apex predator.
